I’ve played around with this (the KIT-CSK-BGT60TR13C). It is a very interesting gadget and the kit doesn’t need much configuration. In an afternoon I made a car detector for my bike that detects the presence of an approaching car from behind. I thought I had a winning startup idea then found out this idea has existed for years. :(

I'd like to know about this product, got more info? Not a bot, just a cyclist who's fed up of drivers who don't care about my safety.

Garmin do one called Varia

Can it detect the distance of the car? If so what's the range/accuracy like?

Could you share how you did it? Interested in this as a hobby

Those implementations might still suck.

They don’t suck. The Garmin one is also a rear light. It integrates with the bike computer to show detections.

When a car approaches from behind you get a visualisation on the bike computer showing you how far away the car is and an audio alert. If the car is approaching fast you get a different audio alert and the light flashes differently to warn the approaching car. It also detects up to three cars.

There might be improvements to be had but the implementation is pretty solid.
